Application fil ed 0ctober,24,1925." Sean mlseso'sq frame, a globe seat at the lower portion of said guard frameand a globe holder, or windbreak as it"i's usually called, at the upper portion of said guard frame; In giving certain signals it is imperative that theair enter the lantern only at points of ingress definitely determined in order that the flame may be sustained, and if during-the giving of these signals a current of air be permitted to enter the lantern between theglobeand its seat the flame will be dimmed, or probably completely extinguished. In an; at} temptto compel firm Contact between the bottom face of the globe and the globe seat so that air may not enter at this point,-1nanufacturers of hand lanternshave been providing the lanterns with the globe holders mentioned above, and have infthis manner, ob-

tained reasonably firmcontaet between the bottom faceof the globeand thefglobe seat; 1 Formerly the globe holder, or, windbreak, of a lantern was not u suallyireinoved from the lantern during the lifefof lantern,

due to the fact vthat the globe holders,1or

" windbreaks, were capable of lastinglas long as the lanterns, and because of this factiogether with the fact that the user of a, 1am

tern used only a single type of globe with his lantern, there was no great necessity for the removal of said globe holders; orwindbreaks. At the presenttime, howev'eiythere are several types of lantern globes on the market and the i globes ot the, difierent types are of different heights, so; that if. a lantern be provided with a globe holder adapted for use with a globe 'of one type; a globe of another type In'ay not be used with' saidglobe holder. In view of the foregoing'Iha-ve'devised the lantern disclosed in the present application, which is constructed that by a very simple operation [the globe holder Lasso-i ciated with thelanternmay'be removedaiid another globe holder substituted for theifirst mentioned globe holder. Because of this arrangement globes of any offthe types new in use maylbe used with the same lantern, it merely being necessary to remove the globe holder associated with the lantern and replace it'with'a different globe holder when it is desired to change from the of globe'to the other; i Another object ofmy vide a lantern having my improved reinov able globe holder associatedtherewith with improved ineansfor controlling the passage of air through the lantei' nbody. 7

' With the foregoing and otherobjeets in view, theinvention comprises th'enovel con use ofone type struction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying draw ings, wherein is shown the preferred en bodiinent ofthe invention. Howfever; itis to be understood that the invention compre hends changes, variations and modifications which come within thescope of the claims hereunto appended.

F'g'L I is a view partly inside elevation and partly 1n vertical section, showing a lantern-constructed in accordance with myinvention said lantern being provided with a lantern globe Iota typenow in general use. I

"II is affragmentaijv vertical section of my improved lantern showing a comparatively short'lantern globe associated there i Fig. IIIis a cross section on line III III ofFig.'I.""

In the drawing'A designates a hand lantern of the type used by trainmen, which lantern is provided with 1 anoil tontholder B secured 1n any 'suitable manner, asffor instance by weldmg to a guard frame (Liand said oil font holderis provided with airinfduction ports D, E designates a' globe seat which is arranged within the oil font'holdor B and is' adapted to receive the bottom i'ace of the la-nternglobe F. The globefseat E is a continuation: of an annular wall" G which is spaced apart inwardlyrfrom the sidewall of the oil font holder to provide an annular air spaceI-I; Located at the upper invention is toproend of the annular'wallG is a row of perforat ons J through which air may pass I fromthe airspa ce H into-the interior of the ltlfi lantern "globe F. ]Thefouter edge of the f globe seatE ,is spaced apart from the-inner face ot theside wallet the oil font holder "B to provide an annular space 'K, and

the upperedge of-saidside wall ofsaid oil font holder is spaced apart from the outer face ofthe adjacent portion of the globe F to provide an annular space L.

In view of the arrangement just described, it is apparent that air may pass. through the air induction ports D into the.

annular space H, and that some of said air will pass through the perforations J into the interior of the globe to sustain the flame therein. If, however, an excessive amount of air passes into the space H, all of said air will not pass through the apertures J into the interior of the globe to disturb the flame therein, but a portion of said excessive amount of air will pass through the spaces K and L to theouter atmosphere. Also if an excessive amount of air passes through the space K into the space H only a portion of said air will pass through the apertures J, the excess passing from the space H through the ports D. 7

M designates the dome of the lantern, which is usually pivotallyv connected to the guard frame G, and said dome is ordinarily provided with a suitable latching device so that it may be fastened in a closed position, but as said latching device and the arrangement of hinging the dome to the guard frame are common, they have not been shown in the drawing and will not be described herein.

N designates my improved globe holder, or windbreak, which includes an annular plate 1 arranged transversely of the lantern. Located at the inner edge of the annular plate 1 is an upwardly extending annular wall 2 at the upper end of which an annular inwardly extended wall 3 is arranged. 4 designates an annular vertical wall which is arranged at the inner edge of the inwardly extended wall 3. The plate 1 and the walls 2, 3 and 4 are preferably, though not necessarily, formed integral with each other. By referring to Fig. I it will be noted that the walls 2 and 3 of the globe holder provide an annular seat for the upper portion of said globe F. 5 designates a coil spring, preferably conical in shape, which is interposed between the top wall of the dome M and the top face of the annular wall 3 .of the globe holder N. The coil spring 5 is adapted to exert downward pressure, thus causing the globe holder to be forced into firm contact with the top face of the globe F, and as a consequence the bottom face of said globe will be forced into firm contact with the globe seat E, whereby the passage of air between the bottom face of the globe and the globe seat is prevented. V

Secured by welding or otherwise to the inner face of the breast portion M of the dome M as an annular flange 6 provided with screw threads, and 7 designates a cup-shaped member having an annular side wall 7 provided with screw threads, and a horizontal the globe holder. N will contact with the face. of the lantern globe, said globe holderbottom wall 7* which overlaps the outer edge portion'of the annular plate 1, said bottom wall 7" being provided with a central opening f considerably greater diameter than the adjacent portion of the globe F, through which opening the lantern globe extends. The diameter of the cup'shaped member 7 is such that the screw threads on the annular side wall thereof will engage the screw threads on the-annular flange 6, thus permitting said cup-shaped member to be screwed on said annular flange, as shown most clearly in Fig. I. It will be: apparent that when the cup-shaped member 7 is screwed on the annular flange 6 asdescribed and shown in the drawing, the bottom wall 7? of said cupshaped member will act as a stop to limit the downward movement of the globe holder N, the plate 1 of said globe holder being adapted to contact with the bottom wall of said cup-shaped member.

- By referring to Fig. I of the drawing it will be noted that the annular sidewall of the dome M is provided with a row of perforations 9 adjacent to the lower end of said annular side wall and a pair of rows of perforations 10 adjacent to the upper end of said wall- Because of the arrangement of the perforations 9 and 10 the vertical ana body of air in a relatively quiet state maintained, which body of air tends to cause a breaking-up, diflusion and checking of the undesirable air currents within the dome, thus preventing disturbance of the flame. Arranged within the dome M and secured to a wall thereof is an annularinclined baffle 11 whieh is intended to deflect upwardly any air which enters the dome through the perforations 10.

- When the dome of a lantern constructed in accordance with my invention, as shown in Fig. I, is being moved to a closed position, top

being moved upwardly to separate the plate 1 from the bottom wall of the cup-shaped member 7. With the parts positioned as de-' scribed, the coil spring 5 will force the globe holder N into firm contact with the top portion of the lantern globe, and the bottom face of said lantern globe will in turn be forced into firm contactwith-the globe seat to prevent the passage, of air at that point. Some of the air necessary to support combustionwithin the globe F will enter said globe through the ports D, space H and ports J, as already explained. will pass through the opening 8'in the bot- Other air i will be arranged when tion of the short lantern tom wall of the cup-shaped member 7 "into the interior of said cup-shaped member,

said air then passing horizontally between the bottom wall of said cup-shaped member and the plate 1 of the globe holder N. Said air will then pass upwardly around the outer edge of the plate 1 into the dome M, with the result that there is always a suflicient amount of fresh air adjacent to the globe holder to maintain the flame when a downward movement of vapor within'the globe is caused. Also, because of the tortuous path traveled by the air, no swiftly moving currents are produced within the dome which would tend to disturb the flame.

Thu-s far I have described a lantern as it a globe of. the. type shown in Fig. I is used. Assume now that a lantern provided with the globe holder and globe, shown in Fig. I were in use, and the user desired to replace the globe with a globe of the short type illustrated in Fig. II. In

this event the cup-shaped-member 7 'would be unscrewed from the flange 6 and the globe holder N would be removed from the lan tern. The globe-holding means employed when a globe of the short type is used comprises, in addition to the globe holder N, which is an exact counterpart of the globe holder N already described, a downwardly extended outwardly flared annular member 12, said member 12 being secured at its upper end in any suitable manner to the globe holder N. The annular member 12 is of such length and its diameter is such at its lower end that it will engage the top porglobe, as shown in Fig. II. Associated with the globe holder N and annular member 12 is a cup-shaped member 7 exactly like the cup-shaped member 7 illustrated in Fig. I, the bottom wall of the cup-shaped member 7 being arranged between the plate 1 of the globe holder N and the outwardly flared wall of the annular member 12, whereby said cup-shaped member is caused to be a part of a unit composed of the globe holder N, annular member 12 and said cup-shaped member. To attach the globe-holding means illustrated in Fig. II to a lantern so that the short type of globe may be used, the lower end of the coil spring 5' is caused to contact with the horizontal wall 3 of the globe holder N and the cupshaped member 7 is then screwed on the screw-threaded annular flange 6, so that the combined globe-holding mechanism is connected to the dome of the lantern, as shown in Fig. II.

It is apparent from the foregoing that it is a very simple matter to change the globeholding mechanism so that one or the other type of globe mentioned herein may be employed, and therefore the necessity that the user be limited to the use of one type of globe is eliminated. It is also apparent that other globe holdersmay be provided which may be used with those mentioned. I I

I'Vhen a lantern globe of the short or any other type is used in connection with my improved lantern the air is controlled as'alreadydescribed in connection with the use of alantern having a globe ofthe type shown in Fig. I.

I claim:

1. A lantern having a dome, a globe, a seat for the bottom face of said spring-pressed globe holder within said dome, and means whereby said globe holder is retained in position'with relation tosaid' dome, the last mentioned means including a cup-shaped member having attaching means whereby said member may be secured in place and a portion which overlaps a portion of said globe holder and limits the downward movement of said globe holder, said member being removable whereby said globe holder may be removed from the lantern.
